Product Overview
KDSL-S500A Three-phase Large Current Generator (hereinafter referred to as Three-phase Current Rise) is the test equipment developed by our company. It combines the advantages of similar products at home and abroad. It adopts numerical control technology and has strong anti-jamming capability. Compared with the previous generation of current rise, the converter made of low power consumption and large capacity self-coupling voltage regulator and high permeability iron core has the advantages of large output power, small size and light weight. It is mainly used for calibration of thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, breaker and protection panel.
KDSL-S500A three-phase large current generator is a high-precision and intelligent AC constant current test equipment specially designed for temperature rise and protection characteristics test of low-voltage electrical equipment. The equipment adopts PLC+IPC control system and is equipped with 10.1-inch true color touch screen, which supports full automatic and manual dual mode operation. Users can automatically complete the whole process of current rising, current stabilization, timing and zero return by setting the target current and time.
In terms of technical parameters, the equipment input is three-phase four-wire 380V ± 10%, 50Hz, rated capacity is 15kVA, three-phase simultaneous or split-phase output 0 ～ 500A continuous adjustable AC current, current stabilization accuracy is ± 0.5%, output waveform is standard sine wave, ripple coefficient is low, and accuracy of transformer is 0.02. Built-in electronic and mechanical over-voltage, over-current and over-temperature protection, automatic zeroing of voltage and current under non-test state to ensure safe operation.
The equipment conforms to GB 7251 series standards and is applicable to temperature rise test of GCK, MNS and other low-voltage complete switchgears, and supports multiple parallel operation; It has the functions of energy consumption measurement, data storage, curve record and report printing, and the software can be upgraded for free. Strong working environment adaptability (- 10 ℃～ 50 ℃, humidity ≤ 90% non-condensation, altitude ≤ 1500 m), overall machine efficiency ≥ 90%, noise lower than 60 dB, widely used in power manufacturing, inspection institutions, substations and scientific research units, it is an efficient, reliable and intelligent solution for large current test.
